Check ink levels and fill the tanks

• Low ink levels can impact print quality. Refill any tanks that are low on ink.
• HP recommends that you use genuine HP ink. HP cannot guarantee the quality or reliability of non-HP ink. If you do not use genuine HP ink and HP printheads, the steps in this document might not resolve print quality issues.
• NOTE:
• Purchase replacement cartridges and other supplies from the HP Store or local retailers.
